1) Your fighting on a bridge. Your goal is to damage Cyclops' cage enough so he can help you. Juggernaut is on ground level with you trying to ram you or stomp you. He's pretty easy to avoid, just listen for him to yell and then move. Magneto's a bit harder; he throws magnetic beams or cars at you that are tricky to avoid. Keep your health up, get a few whacks in on Cyclops' cage, and then dodge. Keep going with that pattern.
2) When Cyclops is free, it's you vs. Juggernaut. Luckily, his helmet got knocked off so he's susceptible to Emma Frost's psychic attacks. She'll tell you when he's free, so just dodge then. Otherwise, treat it like the previous section, hit him a couple of times and then move away. Rinse and repeat.
3) With Juggernaut dispatched, Magneto puts Cyclops back in a cage. You need to run down the street avoiding the massive objects Magneto is sending your way. This is pretty easy, it's either jump over them or move to the far left or right of the screen depending on where they are. When you get to the end of the screen, start attacking Cyclops' cage again. Magneto still shoots magnetic beams, but if you follow the hit and move techniques, their much easier to dodge. When Cyclops is free, he'll start blasting at Magneto who will raise a manhole cover as a shield. However, he is vulnerable from the back, so beat him up! There's nothing to dodge here, so rain down the blows fast and furious.
After a certain amount of damage, Magneto will re-cage Cyclops and throw you down the street again. Just use the same tactics again. Depending on how much damage you inflict, you may have to do this pattern 3 times, but when his health is depleted, the achievement is yours! Whew!

This is near the end of Mission 6: Priorities. Once Pixie dies and Magneto blames Cyclops for the child's death, he and Juggernaut will both engage you and Cyclops in fight. Defeat both Magneto and Juggernaut and the trophy is yours.
Boss Fight - Magneto and Juggernaut's Attacks:
- Charging: Juggernaut will charge at you with momentum.
- Car Toss: Magneto will toss cars towards you.
- Electromagnetic Pulse: Magneto shoots a burst of electromagnetic radiation towards you.
- Elbow Swing: Juggernaut will swirl around and attack you with his elbow.
- Fist Shockwave: Juggernaut will attack the ground with his fist, creating a shockwave.
- Debris Tossing: Magneto will toss debris of buildings at you.
Phase 1:
During this phase you'll have to free Cyclops who's trapped in a metal cage made from debris. You'll also be fighting both Magneto and Juggernaut at the same time. Although not literally, Juggernaut will simply always charge attack you which you can easily dodge with the 
button, while Magneto will be tossing cars at you with his powers. Dodge those too and simply attack the cage that Cyclops is trapped in. Eventually, Magneto will move it way from you as well as attacking you with his Electromagnetic Pulse attacks that he occasionally shoots at you during the fight. The rest of the fight in this phase is the exact same thing over again, so continue dodging both of their attacks and continue to attack the cage in order to free Cyclops.
Phase 2:
During this phase of the battle, you'll be fighting Juggernaut one on one. Juggernaut is still shaken from the damage he has taken from the first phase of the battle, so his attacks are slower than before. He has a few more attacks with him now, but they are easily dodged with the button. Whenever he charges at you, he'll always stun himself which will give you a chance to attack him with your own basic combo attacks. Be careful though because when he regains his stance he'll punch the ground that will create a shockwave. Everything else is pretty much the same thing over again, so continue dodging his attacks and then attack him when he's left wide open.
Phase 3:
This is the final phase of the battle and you'll now be fighting against Magneto. This fight is a little different than before since you'll have to run toward the other end of the field to get to Magneto in order to free Cyclops. While running towards Magneto, he'll be throwing debris of buildings at you. Be very care to note where the debris is dodge-able. If he tosses a metal support beam your way just simply jump over it with the 
button. If he tosses a large pile of debris your way simply dodge it on either the left or right side of the debris pile by simply pressing the button. Once you made it towards the other end of the field attack the cage that Cyclops is trapped in and once Cyclops is temporarily free Magneto will fight Cyclops and will ignore you, so take advantage of the situation and attack Magneto while Cyclops is keeping him at bay. Eventually, Magneto will restore the cage that Cyclops is trapped in and will restart you back on the other end of the field. Everything else is the exact same thing over again, so continue dodging the debris, destroying the cage trapping Cyclops, and continue attacking Magneto until you've finally beaten him.
